As far as the feet going numb..I had the same problems. I guess your like me and you like your bindings super tight. For me it seemed to be happening because i was pulling my foot down on the board too much. I have high arches, so pulling my foot down was putting alot of stress on my foot. I ended up buying a pair of cartels. The top strap on the binding has three holes that it can be moved to for where it actually connects to the binding. I moved it to the highest one near my ankle, so that it is pulling the top part of my foot back, instead of pulling it down onto the board. The cartels also have toe caps, so there is less pressure on my toes and they are also being pulled back and pressing my heel into the binding, rather than pulling my toes down onto the base. Idk..thats what worked for me..can't say for sure if you have the same problem though.
